This ports the changes of 95a59bf206
to this repository.
From that PR:
(mode&S_IFCHR == S_IFCHR) is the wrong way of checking the type of an
inode because the S_IF* bits are actually not a bitmask and instead must
be checked using S_IF*. This bug was neatly hidden behind a (major == 0)
sanity-check but that was removed by [1].
In addition, add a test that makes sure that HostDevices() doesn't give
rubbish results -- because we broke this and fixed this before[2].

The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.

Looks like we had our own copy of the "getDevices" code already, so use
that code (which also matches the code that's used to _generate_ the spec,
so a better match).
Moving the code to a separate file, I also noticed that the _unix and _linux
code was _exactly_ the same (baring some `//nolint:` comments), so also
removing the duplicated code.
With this patch applied, we removed the dependency on the libcontainer/devices
package (leaving only libcontainer/user).
